bool RayIntersection(const vtkVector3d &r, const vtkVector3d &d, vtkVector3d &uv)
Compute the intersection between a ray r->d and the quad.
vtkVector3d ComputeCartesianCoordinates(double u, double v)
Compute cartesian coordinates of point in the quad using parameteric coordinates.
double * GetP00Data()
Get direct access to the underlying point data.
